SPECIFICATION forming part of Letters Patent No. 497,352, dated May 16,1893.

Application filed February 12, 1892. Serial No. 421,280. (No model.)

T at whom it may concern.-

' Be it known that I, GEORGE S. SMALLwooD, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Cabs, ofwhich the following is a full, clear, and exact description, that willenable others to make and use the same, reference being had to theaccompanying drawings, forming a part of this specification, in which tFigure l is a side elevation of a cab structure embodying my improvedfeatures; Fig. 2, a vertical longitudinal section; Fig. 3, a horizontalsection on line 3, Fig. 1, looking in the directionindicated by thearrow; Fig. 4, a perspective of 'the spring platform gear on which thebody of the vehicle is mounted; Fig. 5, a broken-away sectional detail;Fig. 6 a perspective of the iron work supporting the drivers seat; Fig.7, a broken-away elevation and part section of the axle; Fig. 8,abrokenaway vertical section on line 8 Fig. 7, looking in the directionindicated by the arrow; and Figs. 9 and 10 detached details of thegearplatform on which the front wheels turn.

This invention relates to improvements in that class of vehicles knownas cabs of the four-wheel type, and has for its object to provide astructure of this character that will increase the carrying capacitywithout exceeding ordinary dimensions and that will afford convenientingress and egress; the general structural features and arrangement ofthe different parts, combining safety, strength, durability andconvenience, as will be hereinafter set forth.

In the drawings, 12 is the cab-body, 13 the roof or top, 14 the two hindor main carryingwheels, and 15 the two smaller front wheels.

1 The paneling of the sides and ends of the vehicle-body is all straightwork, presenting no convex or concave surfaces. The upper part isprovided with windows, 16, on both sides, the ends of which may belowered inside of the paneling or locked in a closed position asrequired. The windows are provided with curtains, 17.

The hip-roof terminates in the monitor top,

18, having straight vertical inclosing sides and an overhanging hiproof, the sides having openings therein protected by small windows 19,which may be opened to afford ventilation. This monitor top alsoprovides space for a lamp to be suspended on the inside. The roofoverhangs and protects the sides from the drip. This form or style ofroof in a cab presents a unique appearance.

The two doors, 20, are located on each side near the front end, arehinged as at a, and open toward the front. The front wheels are setcloser together than the main wheels and track inside of the same, sothat the doors may open clear back parallel with the sides of the body,aifording convenient ingress and egress, and are also out of the way ofany passing vehicles when in an open position. The upper parts of thedoors are provided with curtained windows 21.

22 are steps, properly supported from the bottom of the structure. Thefront wheels are of a less diameter than the hind wheels.

The arrangement of the seats is clearly shown in Fig. 3. The double backseat, 23, is stationary and extends from side to side. Connected withthis double seat is a temporary seat, 24., for the accommodation of achild. This seat is adapted to fold underneath the permanent seat out ofthe way when not required for use. The two side seats, 25 and 26, andthe front seat, 27, are hinged at their back edges to the lining of thebody and have legs, 28, hinged to the front edges to support the same ina seating position, and fold underneath and thus permit of these seatsbeing dropped down parallel, as shown in Fig. 2, with the inclosingsides and out of the way when there are but one or two passengers, thusaffording ample room for baggage and parcels. This arrangement providesseating capacity for six persons and leaves passageway for ingress andegress when all the seats are in position for use. The body willordinarily be of the rectangular form in horizontal section, shown whichtogether with the arrangement of the seats and doors will afford thegreatest carrying capacity within certain limited dimensions. The mainaxle,

29, is of the bent type, and permits the lower part of the body to setdown well below the center of axis, bringing the steps within convenientreach and doing away with the liability of the vehicle overturning.

The supporting-platformgear consists of the two parallel side springs,30 and 31, and the companion transverse springs, and These springs arearranged in the form of a square and are loosely connected at theirrespectiveends and corners. The side springs are placed with the concavesides upward, and rest,0n the pillow blocks 7 5, which in turn rest uponthe axle-bar, near their longitudinal centers and are secured thereto bybolts 34. The transverse springs have the convex side upward; the endsextending under the corresponding ends of the side springs and beingloosely suspended therefrom, as shown in Fig. 4. To the respective endsof each of the side springs are pivoted the curved links or loops,

35, hanging downwardly, and which interlock with companion links, 36,projecting upwardly and pivoted to the ends of the transverse springs,forming a swivel or universal jointconnection, so that the springs yieldin any direction, and automatically adjust themselves to anyrequirement. The companion transverse spring-bars, 37, are seated on thetransverse springs and are seen red thereto by clips, 38. These bars areperforated to receive the bolts securing the cab-body. The springscomposing the platform are all of the semi or half elliptic form.

The form of axle shown is liable to bend or break across the corners. Itis, therefore, necessary to strengthen the same at those points. This isdone by means of an inside corner or angle-iron, 39, and an outsideangle-iron, 40, shown in Figs. 4, 7 and 8. The lower end of the insidecorner iron or irons is provided, at each side, with the upturned lip,

41, to lock the 11 cad-end of the fastening-clips,

42, in place. The lower ends of clips 42 are connected underneath theaxle by clip-bars, 43, formed on the lower end of the outside angle-ironand secured in place by nuts 44. Clips 42 also embrace the side springsand assist in retaining the same in proper position. The upper bar-end,45, of the inside corner iron is perforated for the insertion of thethreaded ends of clip 46 locked in place by nuts 47. This clip embracesthe upper end of the outside corner iron which is provided with theoverturned lip, 48, (Fig. 7,) thus firmly securing the upper ends of thecorner irons with reference to the axle. By this arrangement theaxle-bar is greatly strengthened at the weak points and the side-springsfirmly fastened at their longitudinal centers. One end of the steadyingor stiffening bracerod, 49, (Fig. 5,) is pivoted to plate 50, bolted tothe under side of the body. The opposite end is pivoted to plate 51bearing against the under side of the axle, and secured by clip 52embracing the axle. There will be two or more of these brace-rods usedin the construction, located both forward of and back of the axle.

The drivers seat, 53, is located in front of the cab-body over the frontwheels, and the means employed in supporting the same and the fifthwheel gear-attachment will next be described. The two elliptic springs,54 and 55, are located just inside of the respective front wheels; theunder half being secured to axle 56 by clips 57; and the upper half tospring-bars, 58, on which rests the lower half, 59, (Fig. 0,) of thefifth-wheel gear. The upper half, 60, of this gear (Fig.'10,) is securedto the under side of the front part of the main supporting-irons, 61 and62. These irons are of the shape shown in Fig. 6, the back horizontalends running under the cab-body andbeing bolted to the two inside sills,63, occupyin g the relative position to the outside sills of the fiooras that shown by the broken-away part in Fig. 3. These irons turnupwardly at right angles for some way, and are bolted to the lower frontpart of the body, then curve to the front downwardly and form the archedpart or goose-neck b,then extend horizontally across the fifthwheel-gear and terminate in the upwardly inclined ends (I. This forms avery strong connection and support between the cab-body and the frontwheel-gear platform and the drivers seat. The arched parts of the ironsprovide room for the front wheels to turn in under and thus permit ofthe vchicle being turned within limited space. The upturned rear ends ofseat-irons, 64 and 65, are bolted to the cab-body and from thence extendforward and down and are bolted to the horizontal and terminal parts ofirons 61 and 62, forming a support for the foot-rest 66. The lower endsof tubular posts, 67, are mounted on the arched part of irons 61 and 62;the seatirons resting on the upper ends of these posts, and the partssecured by bolts 68. The posts are connected by a strengtheningcross-bar 69. Byhaving the front wheels track inside of the hind wheels,ample room is provided for doorspace, and the loose earth picked up bythe wheels is not thrown back on the fenders of the hind wheels, so thatingress and egress may be effected without damage to the clothing.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A cab or vehicle body of a rectangular form in horizontal section,having straight vertical inclosing sides,and provided with anoverhanging hip-roof terminating in a monitor top also having anoverhanging hip roof and straight vertical inclosing sides in which areventilator openings, substantially as set forth.

2. A cab or vehicle body having straight side walls, swinging doorshinged to the re spective sides of the body at the front corners, hindwheels tracking outside the body, and front wheels of less diameter thanthe hind wheels and tracking inside the width of the cab body, wherebysaid doors may be swung open parallel to the inclosing sides withoutinterfering with the front wheels, substantially as set forth.

3. In a cab or vehicle, the combination of the bent axle bar, the sidesprings, the inside angle corner irons, and clips connecting the and theclips for clamping the springs be:

tween the horizontal flanges of the irons and the axle and pillownlocks, substantially as described. 7

6. The combination of the bent axle bar, the pillow blocks, the sidesprings resting on said blocks, the inside corner angle-irons overlyingthe springs, the outside corner angle-irons,

the clips for securing the verticalfianges of the inside and outsideirons to the upright parts of the axle bar, and the clips for clampingthe springs between the horizontal flanges of the inside irons, and theaxle and pillow blocks, substantially as described.

7 In a cab or vehicle of the class described, the combination of thearched companion irons, the companion seat irons, secured at their rearends to the cab-body and at their forward ends to the corresponding partof the arched irons, the posts, supporting the seatirons, the bolts,rigidly securing these parts, and the transverse bar connecting saidposts, substantiallyas setforth.

8. The combination with the vehiclebody and the gear platform over thefront wheels, of the arched companion irons, the companion seat irons,secured at their rear ends to the cab body and at theirforward ends tothe corresponding parts of the arched irons, the posts supporting theseat irons, the bolts rigidly securing these parts, and the transversebar conneeting said posts, substantially as'described;
